How to prevent cigarette butts from catching fire

Although cigarette butts are small, they can be harmful. Their surface temperature is between 200-300 degrees Celsius, and the center temperature can reach about 700-800 degrees Celsius. The ignition point of general combustible materials (such as paper, cotton, firewood, wood, etc.). ) are between 130-350 degrees Celsius, which is lower than the temperature of cigarette butts, so cigarette butts can ignite most substances, so littering cigarette butts is easy to cause fires. After smoking, you should "strangle" the cigarette end and put it in an ashtray or nonflammable appliances such as metal and glass. Don't throw it about, and don't smoke in non-smoking places.
